The Arduino Ethernet Shield allows an Arduino board to connect to the internet. It is based on the
Wiznet
W5100
ethernet chip (datasheet). The Wiznet W5100 provides a network (IP) stack capable of both TCP
and UDP. It supports up to four simultaneous socket connections. Use the
Ethernet library
to write sketches
which connect to the internet using the shield. The ethernet shield connects to an Arduino board using long
wire-wrap headers which extend through the shield. This keeps the pin layout intact and allows another
shield to be stacked on top.
The latest revision of the shield adds a micro-SD card slot, which can be used to store files for serving over
the network. It is compatible with the Arduino Duemilanove and Mega (using the Ethernet library coming in
Arduino 0019). An SD card library is not yet included in the standard Arduino distribution, but the
sdfatlib
by
Bill Greiman works well. See
this tutorial from Adafruit Industries
for instructions (thanks Limor!).
The latest revision of the shield also includes a reset controller, to ensure that the W5100 Ethernet module
is properly reset on power-up. Previous revisions of the shield were not compatible with the Mega and need
to be manually reset after power-up. The original revision of the shield contained a full-size SD card slot;
this is not supported.
Arduino communicates with both the W5100 and SD card using the SPI bus (through the ICSP header).
This is on digital pins 11, 12, and 13 on the Duemilanove and pins 50, 51, and 52 on the Mega. On both
boards, pin 10 is used to select the W5100 and pin 4 for the SD card. These pins cannot be used for
general i/o. On the Mega, the hardware SS pin, 53, is not used to select either the W5100 or the SD card,
but it must be kept as an output or the SPI interface won't work.
Note that because the W5100 and SD card share the SPI bus, only one can be active at a time. If you are
using both peripherals in your program, this should be taken care of by the corresponding libraries. If
you're not using one of the peripherals in your program, however, you'll need to explicitly deselect it. To do
this with the SD card, set pin 4 as an output and write a high to it. For the W5100, set digital pin 10 as a
high output.
The shield provides a standard RJ45 ethernet jack.
